How to get all checked items from a ListView?

by

The other answers using SparseBooleanArray are nearly correct, but they are missing one important thing: SparseBooleanArray.size() will sometimes only return the count of true values. A correct implementation that iterates over all the items of the list is:

SparseBooleanArray checked = list.getCheckedItemPositions();

for (int i = 0; i < list.getAdapter().getCount(); i++) {
    if (checked.get(i)) {
        // Do something
    }
}
